Norwood, Mass., U.S.A. 5925 MY FRIEND AND TEACHER JOSIAH KOYCE PREFACE THIS volume on metaphysics is the sequel of a volume on the theory of knowledge, entitled "Truth and Reality," which was published in 1911. The two volumes furnish a survey of the field of general philosophy from the point of view of pragmatic realism. This attitude which the author has been champion- ing for several years is an attempt to apply scientific method to philosophic problems. The term pragmatic is used in the sense which was first advocated by C. S. Peirce, and which is defined by the author in his own terms in "Truth and Reality." As applied to metaphysics the pragmatic method means that we must judge the nature of reality, in its various grades and complexities, by the consequences to the realization of human purposes, instead of by a priori assumptions. Some may pre- fer the older adjectives of "empirical" or "critical"; but these terms seem definitely associated with certain historical doctrines, and a new term seems to be preferable in designating the scientific tendency of to-day. There is need in every age of retranslating the perennial problems of philosophy into terms of living human interest; and the author hopes in a meas- ure to further this movement at the present time through these volumes. In "A Realistic Universe" the author has tried to make vital the fundamental problems of metaphysics in terms of our present thought-world, without the cant of the past, but with a deep sense of indebtedness to the masters of all time. While the book is intended primarily for the philosophic stu- dent, the aim has been to make the style as clear and simple as the problems would permit. In the use of scientific material, an effort has been made to find sources which would be intel- ligible to the layman rather than to make an appearance of erudition. Some portions, such as the introductory chapter and part five on Form, may be of special interest to the general reader. vii viii PREFACE The work as it now stands, imperfect as it may be in execu- tion, has had a long history. The oldest portion is that re- lating to time. The author's theory of time was first outlined in a paper on that subject, written for Professor Royce's Semi- nary in 1897-1898. It found fuller statement in his doctor's thesis on "The Concept of Time" in 1899; and was further expounded in a monograph entitled "Time and Reality," published in the Psychological Review monograph series, No. 26, in 1904. A brief statement in the Journal of Philosophy, Psychology and Scientific Methods in 1905 has been partly made use of in this book. As there has been no material change in the author's attitude since the publication of the monograph, the reader may be referred to this for supplementary treatment. Preliminary studies of the concepts of Space, 1906, Con- sciousness, 1908, and Energy, 1908, have been published in the Journal of Philosophy, etc. While the main view-point re- mains in each case, the material has been thoroughly restated and should be judged by its present form. The same applies to the article, "The Ought and Reality," which appeared in the International Journal of Ethics, 1907, and which in the present volume has been restated under the title "Form and the Ought." Other papers which have been made use of, in whole or in part, are: "Do Things Exist?" 1912, and "In- dividual and Social Minds," 1913, from the Journal of Phi- losophy, etc.; "Knowing Things" from the Philosophical Re- view, 1911; "Knowing Selves," Psychological Review, 1912; "The Identity of the Ideals" from the International Journal of Ethics, 1912; "A Rehabilitation of Teleology," under the title of " Teleological Idealism," from the Harvard Theological Review, 1912; "Pragmatic Realism — the Five Attributes," under the title of "The Five Attributes" from Mind, 1913; and "The Divine Fivefold Truth" from the Monist, 1911. The author wishes to express his appreciation to these journals for their cooperation and encouragement, which have meant a great deal to a man working in comparative isolation. The work, however, is in no sense a compilation of articles, but was early conceived as a systematic unity, though he wished the advantage of the objectivity and time perspective furnished by preliminary publication, as well as the incentive that comes PREFACE ix from feeling a part of the social consciousness with the informal reactions thus made possible. In this connection, he wishes to express also his appreciation to the Western Philosophical Association, before which many of the preliminary studies were first read. As regards his indebtedness to other workers in the field, the book itself will have to bear testimony. Among philosophers, his indebtedness is greatest to the standard masters, not only because of their intrinsic merit, but because they have been most accessible. In all things speculative, we must still sit at the feet of the Greek masters. His first systematic training in philosophy the author received under the tutelage of the great German idealists, Kant, Fichte, and Hegel, thanks to his first guide in philosophy, James Seth. From the British empiricists he has learned, he hopes, a homely regard for the facts of experience. Of French thinkers, he owes most to Poincare, whose phenomenal grasp of science and transparent genius place him in a class by himself among philosophers of science. Of the author's immediate environment, he hopes there may appear in this work something of the inspiration of the great leader in American philosophy, William James, and of its recent laureate, Josiah Royce. Nor could one escape the vitalizing influence in our country of its great teacher, John Dewey, and the Chicago School. . When the author was working out his theory of time, he did not have the good for- tune to be acquainted with the brilliant work of Bergson on that concept. Not even William James seemed conscious of Bergson's contribution in the later '90's. While the author's theory agrees with that of Bergson in aiming to establish the reality of time, both the fundamental intuition and the method are different. The concept as set forth in this volume, and in previous discussions, must be regarded, therefore, as a different concept. In the later revision of the work, the author has been stimulated by the recent realistic discussions, both in Great Britain and America. Since the first draft of this work was completed in 1912, and most of it antedates the movement some- times called " the new realism," perhaps more properly called analytical realism, its development has been comparatively independent of this movement, and has little in common with X PREFACE it either in spirit or method. As between the extreme anti- intellectualism of Bergsonism, and the extreme intellectualism of analytical realism, pragmatic realism steers a middle course. While maintaining, as against analytical realism, that reality is more than a congeries of abstract logical entities, it insists as against intuitionism on the relevancy of thought to reality. Only thus could thought furnish valid leadings in our practical and theoretical conduct. This attitude is in line with com- mon sense and empirical science. The present work does not aim to be a compendium of cur- rent literature. There are books which serve this purpose in an admirable way. It must be judged rather as a personal reaction to the permanent problems of human experience, for, whether we will it or no, our systems are after all personal re- actions. If they are sincere and thorough, we may hope that they will further the total movement of truth. The time seems peculiarly auspicious for such an attempt at synthesis. While there has been much of suggestion and inspiration in recent discussion, the constructive efforts have been disappointing. This is due, no doubt, to the magnitude of the task. In the complexity of modern thought and life, we cannot perhaps hope for an Aristotle. What could once be accomplished by in- dividual genius, must now be carried out piecemeal by the interstimulation and supplementation of a collective mind. The author will be satisfied if he can count as even an infinites- imal part in this infinite task. As this work has grown up for the most part on the western prairies, may it reflect the homely sanity of the great West. NOBTHFIELD, MINNESOTA September 14, 1916 TABLE OF CONTENTS INTRODUCTION.

RETROSPECT — THE FIVE ATTRIBUTES . . . 385-404 INTRODUCTION THE MEANING OF METAPHYSICS The Place of Metaphysics, — In this age of narrow special- ization and absorbing immediate interests, it is well that we should try to recover what Plato called " the love of the whole- ness of things, both human and divine." By doing so, we shall gain greater insight into our special problems and greater sanity in practical life. For philosophy is merely sustained thinking about the things that are of vital and permanent con- cern to the human race in the whirl of circumstance in which we find ourselves. There are many reasons for the disrepute into which the noblest of sciences has fallen in our own day. One of these is the bias of words. Metaphysics has been confused with ob- scurantism and occultism ; and professional philosophers are in a large degree to blame for this. They have been victims of a traditional vocabulary which once was significant in the history of thought, but which has ceased to be relevant to our special matrix of problems. The tendency has been to substitute counters for things, antique phrases for clear and distinct ideas. Whenever philosophy has been vital, it has always followed close upon the heels of science and human in- terest. It was so that metaphysics originated as a science in the days of Aristotle. It is so that it has maintained itself ever since, whether translated into the theological atmosphere of the Middle Ages, or into the scientific spirit of the age of Descartes and Locke. To be vital to-day, metaphysics must clarify our own scientific and social problems. Another reason is to be found in our narrow emphasis on the practical. The most dangerous sophist in any age, as Plato pointed out, is the public sophist, — the prevailing emphasis of the social mind. To-day, the emphasis is on immediate material results rather than on the calm contemplation of the jdii xiv INTRODUCTION meaning of things. We are bent on producing weather rather than on examining its whither. We seem to have raised weather enough ; and if we persist there will be nothing much to con- template but ruins. Bitter after-reflection may teach us that the question is not merely of efficiency ; but to what end ? Not the least important reason is the slovenliness and laziness in our present day thinking, which, particularly in our country, is the outcome of our new education. This is rapidly making this generation incapable of sustained reflection. Religion has become a matter of sentimentalism instead of the systematic interpretation that characterized the Middle Ages and the Reformation. In philosophy we have substituted intuition for serious reflection; in science, narrow specialization for comprehensive perspectives. There is danger that we may prove unfit for the task of meeting the great social problems of the day, which will require the most stubborn sort of thought for their solution. In such an age, we need to hearken back to Plato's warning that things can only be set right when philoso- phers are kings; and philosophers are men who can think in terms of the whole. Indeed, the great masters, whether in the world of thought or of action, have always been philosophers, even if they have not always been conscious of the fact. Though we may neglect metaphysics, we cannot get away from it. Being of the very nature of reflective thought, it can say: "When me you fly, I am the wings." Metaphysics, as Comenius pointed out, begins at the mother's knee. "Thus, from the moment he begins to speak, the child comes to know himself, and by his daily experience, certain general and ab- stract expressions; he comes to comprehend the meaning of the words something, nothing, thus, otherwise, where, similar, different; and what are generalizations and the categories expressed by these words but the rudiments of metaphysics?" We are thus introduced by social suggestion to the distinctions of things and qualities, mind and matter, cause and effect, space and time, the conscious and unconscious. We are taught to construct a scale of values and to believe in a world of ideals. Our common sense and science are shot through with meta- physical concepts. The difference between such metaphysics and that of the philosophic thinker lies in the degree of thorough- INTRODUCTION XV ness with which we pursue such matters. It is clear then that metaphysics has a permanent claim on human nature. We may well agree with Aristotle: "All the sciences indeed are more necessary than this, but none is better." It must be said, too, that in spite of the shallowness of our thinking, there is, in our age, a strong feeling for ideals, a sound faith in melioration which persists undismayed in the baffling complexity of our problems, and which furnishes the one ray of hope in a great international tragedy — a promise of better things. It is at heart an idealistic age — an age of reconstruc- tion, of profound awakening to human claims. This should give philosophy a new opportunity in the building out of the meaning of life. The Presuppositions of Metaphysics. — A few years ago it was fashionable to advertise a philosophy without presuppositions. This would indeed be radical empiricism; but it would be suicidal at the outset, since to philosophize we must think ; and thought has its own presuppositions which are implied in all its procedure, whether metaphysical, or more narrowly scientific. Metaphysics, as a systematic treatment of ex- perience, impllies~TogicT It assumes that there are valid rules of thought, that we can arrive aT common understandings. BmTmetaphysics, as a final evaluation of experience, implies more than the laws of thought. It implies a faith in their fitness or relevancy to our world. We must trust the instru- ment at the outset. The mute faith in the possibility of knowl- edge is the very spring of the process. This is fundamentally an attitude of the will. But it is a constructive attitude, and justifies itself in the progress of human experience. To criti- cize the instrument in the abstract is at best a futile task. Some philosophers have concluded, from certain a priori con- siderations, that thought is contradictory or inadequate. Kant finds it suspicious that thought is equipped with certain cate- gories at the outset. These seem somehow arbitrary; they carry on their face no guaranty that they fit into the empirical structure of things. The British agnostics have noted the relational character of thought, and have assumed for some traditional or temperamental reason that reality is the un- conditioned or non-relational. But the fruitfulness of such xvi INTRODUCTION thinkers as Kant and Spencer lies, not in their a priori assump- tions, but in the contribution which they have made to the correlation of the values of experience by means of the instru- ment which they mistrusted. Somehow, the laws of thought must be the laws of things if we are going to attempt a science of reality. Thought and things are part of one evolving matrix, and cannot ultimately conflict. Hegel here shows himself a saner pragmatist. The cate- gories of thought must be tested by their success in actual use. If the values of experience can be correlated and unified in terms of the categories of thought, then thought requires no other credentials. Its validity is guaranteed by the outcome, not by any a priori test, which is a mere hewing in vacuo. We may object to Hegel's own formulation of the fundamental concepts; we may not share his confidence in the abstractly logical character of the process thus to be manipulated. His triadic relations may appear arbitrary and stilted. His sys-' tern may seem too much like the staging of abstract categories, and as lacking real movement and zest. But that, after all, is because he fails as measured in terms of his own criterion — the success of thought in realizing its concrete leading from part to part, from corridor to corridor within the complex structure of reality. The real world is more fluent and complex and baffling and tragic than Hegel's logic with all its interesting paradoxes could comprehend. His faith, however, is invincible and immortal. Let us give thought a fair field at the outset. Let us not discredit the instrument because it has a character of its own. It could not be an instrument otherwise. The universe in its own selective movement forged it, in the long ages, for just such a world as ours and such needs as ours. The possibility of its conquests are but dimly foreshadowed as yet. The important thing is that our concepts shall work; that they shall blend into the concrete process of life for which they are made, and out of which they are selected. If they are relevant, they cannot be arbitrary, — not "appearances" in the sense of unreal, even though they are at best abstract aspects of reality. They are not only convenient tools, but part and parcel of the world which they enable us to predict, use, and appreciate. To criticize thought independently of its INTRODUCTION xvii function in experience is as senseless as would be a baby's criticism of its fitness for walking by an abstract examination of its anatomy. The impulse to walk and the development of the anatomy are part of a single movement. We learn to walk by following the impulse to walk ; and we learn the nature of things by repeated efforts to use the instrument of thought. In each case, the implied faith is justified by its success. While we must have faith in the relevancy of thought, we must not prejudice the outcome of thought's experiment by our assumptions. Perhaps it is not true that the object, in order to make a difference to our reflective purposes, must it- self be purposive through and through. Perhaps, on the other hand, reality is more rational than our ignorance and im- patience assumed. Perhaps there are no simple entities, ex- cept as we so treat them for our pragmatic purposes. Perhaps relations cannot be resolved into either the internal or external type exclusively. Perhaps our values may be guaranteed, or at any rate have all the guarantee they do have, in a pluralistic and temporal world as well as in an absolutistic and eternal. At any rate we must be free to follow the leading of our ex- periments. The postulates of thought and the postulate of their relevancy seem to be all that are required in so funda- mental an inquiry. And these too must be justified by their success, for the laws of thought can rise to clearness and dis- tinctness only through their use. For the dogmatic method, too often applied in matters of philosophy, we must substitute the empirical or critical method — the method which the special sciences have proved so fruit- ful in their own domain. It is not the province of metaphysics to dictate to reality what it must be, but to discover its funda- mental meaning. It is only when pursued in this spirit that metaphysics can take rank as a science, and, at least in its ideal, as the science of sciences. THE FUNCTION OF METAPHYSICS It has been asserted that the acceptance of philosophies has nothing to do with their truth, but with their congeniality to people's passions and prejudices. This seems indeed to be true to a large extent in our imperfect and uncertain evolution, xviii INTRODUCTION where our mutual blindness plays such a large part in the acceptance of beliefs. It often seems, in the snail's pace of the many, that ideas only gain acceptance after they are an- tiquated and then as obstacles to further progress. Thus Aristotle is accepted as a dogma to defeat the progress of modern science. It would seem that society, by the very law of its development, is bound to feed upon the illusions of yesterday. Its progress is ever unwilling. It is ever moving with its back to the light. It is ever making martyrs of its prophets. In thus arraigning society, however, we are losing sight of the fact that human nature has other claims to satisfy beside those of pure truth. The primitive law of society, as of the individual, is self-preservation ; and to this end it must ever watch with jealous care the introduction of new gods. In- dividual insight is ever the disturber of the social equilibrium, which insists on standardized beliefs. The human Prometheus, therefore, must pay the penalty of his profanity in stealing fire from heaven. The new claims must be put upon the rack and tried out with reference to the other claims of human nature, before the social instinct of self-preservation is set at rest. It is useless to rail against this law of nature. We are all part of it. Our tolerance extends merely to the trivial. When any profound revolution is threatened, we agree that it is expedient that one man suffer rather than the whole people perish. If we were merely logic machines, materialism as a philoso- phy would doubtless triumph. The mechanical view has cer- tainly the advantage of simplicity. But the simplest theory is not necessarily true. A theory must be sufficient as well as simple. It must be capable of harmonizing all the claims. And the facts may be richer than materialism, with its mathe- matical models, assumes. The universe is not merely a place for the play of our logical faculty. It must in some way own our other ideal demands. Philosophies must do justice to our whole human nature. They must satisfy our emotional and volitional nature, as well as our intellectual. And society has always regarded logic as secondary to its security and happiness. We build philosophies and air castles for the spirit, as we build houses for the body, to keep out the blast INTRODUCTION xix and cold of an unfriendly and fickle cosmic weather. Philosophy has its value in appealing to our sentiments of courage and justice, of love and hope, as well as to our sense for fact. When we are hit by the blind vicissitudes of fortune, whether the scourges of nature in the form of pestilence and famine or the human curses of envy, hatred, and malice, it is well if we can say with Socrates : "No evil can happen to a good man either in life or after death." And so it is that the agnostics and sceptics, brilliant though they may have been, and though the advantage of logic has often been on their side, have scarcely counted in the history of society. They are the mere curios of the philosophical closet. If they have been preserved, it has been only through the social indignation and refutation which they have occa- sioned. The effective systems of philosophy are tremendous affirmations of faith — faith in human society and its under- lying ideals. While one set of facts may apparently be as true as another, some facts are worth more than others in the economy of human life. Since truth is a program of life, such emphases as open up the future, as furnish the largest scope of activity, naturally prevail in human interest. Hence, idealism will always triumph over materialism, even though the latter may be more economic ; for philosophy exists in part for ennobling life, for enhancing the prospect, not merely as the echo of a day that is gone, of a life's sun which has known its setting. Idealistic systems have, one and all, been romantic exaggera- tions. But they invite to effort and melioration, to faith and hope: "God's in his heaven, all's well with the world." The fault lies in us, and can be cured. The exaggeration of promise serves as a compensation for the seeming bankruptcy of our temporal life. The greater the odds, the greater is the in- toxication of hope that is required to balance. Hence idealism has flourished best in the face of national crises and misfor- tunes, whether in an Athens stripped of its power, an exiled Israel, or an over-run Germany. It is then that the kingdom- not-of-this-world stands out in strongest relief. The roman- ticism of youth will always be indispensable for overcoming the disappointments of our work-a-day life. The faith of a Plato that only the Good is ultimately real; of a Kant that XX INTRODUCTION our moral consciousness legislates to the universe ; of a Fichte that the world of sense, stubborn though it be, is but the stag- ing and raw material for realizing the moral law; of a Hegel that, in spite of all seeming blindness and chance, the world is a rational whole ; of a Royce that loyalty to the ideal is the supreme key to reality — all these are noble poems which, even by their exaggerations, will continue to inspire the race, long after the more rigid systems are forgotten. Friendship, love, and hope require idealization to live ; and so we need the ex- aggeration of the romanticists. Since in ultimate things we can know so little that is true, human nature will insist on hold- ing fast to that which seems to it a good, trusting that in the end this may lead it nearer to the true. Is this idealizing function of human nature altogether an illusion? It must exist for a use, prominent since it is in the evolution and welfare of man. There are two views possible of this function. We may regard it as a sort of protective covering provided by nature for a highly sensitive animal against the icy blasts of circumstance, to shield him against inevitable disappointments; or we may regard it as the small voice of the universe, however imperfectly understood. In the former case, it becomes indeed an unaccountable illusion, which fails of its purpose the moment man ceases to be the dupe 'of na- ture's trick, and learns the profound lesson that there are only atoms and the void. In the latter case, it points to the true vocation of man. Since the function of both art and metaphysics is to idealize life, to grasp its deeper meaning, the relation between them has often been emphasized. It has been pointed out that their motive is fundamentally the same, viz. the discovery of har- mony. For Poincare" it is "harmony expressed by mathematical laws. It is this harmony then which is the sole objective reality, the only truth we can attain ; and when I add that the universal harmony of the world is the source of all beauty, it will be under- stood what price we should attach to the slow and difficult progress which little by little enables us to know it better." * But though the same feeling for unity and fitness underlies both activities, neither the method nor the result are the same. 1 " The Value of Science," p. 14. INTRODUCTION We cannot agree with those who would substitute the mystical and artistic approach for the logical, and who insist that, in order really to know, we must supersede thought by intui- tion, logic by immediate appreciation. It is true that both in art and metaphysics there must be analysis of the primitive situation. In each case, these aspects must be supplemented with the concrete fullness of experience in the realized purpose. I But in art, this supplementation must take place by means of spontaneous suggestion, in metaphysics by awake and articulate recognition. In the former, the instrument or leading fuses with the totality sought; in the latter, the externality of the instrument to its outcome is emphasized. In art, the selective activity is for the sake of permanent objects of enjoyment; in metaphysics, for the sake of understanding. Metaphysics is science, not art. Problems of Metaphysics. — Metaphysics has been spoken of as the common corridor of the specific types of idealizing ac- tivity. As a corridor it serves a double purpose. It opens up into the special compartments of truth. It implies, and fur- nishes the inspiration of, the special sciences. It is the expres- sion of the underlying faith which leads man to seek for unity and wholeness in our seemingly chaotic world. It is indeed the oldest of the sciences — the mother of science. It is also the terminus and clearing house of the specific activities for truth. It deals with the common and overlapping problems, left over by the special sciences. It is thus the heir of the sciences. It must ever be present as a regulative ideal in all our search for truth. It indicates the ultimate direction and meaning of all our ideal striving. Historically and logically, therefore, it is the Alpha and Omega of our attempts to understand and ap- preciate our world. Like a perspective from some high moun- tain, it necessarily blurs details in emphasizing the main con- tours of the landscape. At best, it is an outlook rather than an absolute scheme, a temper of mind rather than a finished re- sult. But as such, it corrects our partial emphases and con- duces to sanity. Often misunderstood, it cannot be avoided so long as we have last beliefs, and act upon them. It has been customary to divide the problems of metaphysics into two types — ontology and cosmology. Ontology has xxii INTRODUCTION dealt with the problem of being or stuff. It has attempted to answer the question whether reality consists of such stuff as dreams are made of, or the seemingly solid stuff of sense quali- ties, or a combination of the two. It has also examined into the factual relations of things, such as causal, spatial, and tem- poral relations. Cosmology, on the other hand, has been con- cerned with the ultimate form, purpose, or meaning of our world, and has been closely allied with religion. The division does not seem fortunate, since the aspect of form or purpose has as real an existence as the stuff aspect and its factual relations. Hence there has necessarily been a great deal of confusion and overlapping. The division of problems in this book is based upon certain ultimate and generic concepts, viz. energy, consciousness, space, time, and form. Those who cling to the traditional division of ontology and cosmology may find solace in the fact that the first four parts, viz. those that deal with energy, consciousness, space, and time, may be classed under the traditional heading of ontology, and the fifth part, which deals with form, under the heading of cosmology. The old heads, however, have little pragmatic value and should give way to a more scientific division of problems. I have departed from the old custom of giving a cut and dried summary at the beginning. Instead of that, I have tried to give a concrete picture of the problems in the first chapter. Philosophy must begin with intuition, however severe may be its method. It is hoped that this imaginative statement may be a help to the elementary student, even though it offend the pedant. A more technical summary will be found in the last chapter, and the professional philosopher may prefer to turn to it at the outset. A REALISTIC UNIVERSE CHAPTER I PERSPECTIVE: THE DIVINE FIVE-FOLD TRUTH IT is the holy stillness of night. The world with its busy cares is asleep. And that is the witching hour of divine philos- ophy. In the silence, a Spirit comes to me and bids me write. Is it inspiration ? Or is it the fever of the night's vigil ? I do not know. But, somehow, my soul seems calm and I seem to see in a sort of mystic way the meaning of things which were dark before. At least I will obey the muse to-night and trust in the leading of the Spirit, for this seems like no human in- sight. Tarry, sweet Muse. The night is young. I would fain revel in glorious discourse. At other times I have spoken through the long processes of logic. To-night, I would fain speak as an oracle. The Divine Truth of "Being" First of all, there comes to me the old and divine truth of "being" — not static, inert "being," but constellations of energy, conscious and unconscious, interlocking and interact- ing in space. Worlds rise and dissolve like smoke wreaths, with ever- varying cadences. Yet through all the shifting forms laws prevail ; and we gnats of a day, that are borne upon this stream of change, can, to a degree, forecast the future from the lingering shadows of the past. In each stage of creative trans- mutation, reality speaks to those that can understand : " that am I." In spots, and for a cosmic instant, energy collects and condenses into material centers. These centers, through their mysterious, dynamic threads hang together as a whole. You can pass on the light beams from one to the other, even to the last. They dance together in mathematical rhythm in cos- mic space; and, in the infinite ages at least, carry on a fair exchange of measure for measure. And part, at least, have life and mind and can catch the meaning of their relationship. 3 4 A REALISTIC UNIVERSE Spinoza, the God-intoxicated, had a vision of the universe as two winding corridors ; each variegated fresco of one is imitated in the other, for the order of thought and things is the same. Each voice in one has its echo in the other, for the mind is the idea of the body. Proceed as you may through the infinite windings of one, no window opens into the other. But if eye hath not seen nor ear heard, and if it hath not entered into the thought of man that there is another half-world, is it more than the shadow of man's mind? And if any one doubts the exist- ence of the other corridor, who shall prove it? Spinoza, in the passion of his fancy, supposed that if things exist, and if we become conscious of things, then things must be repeated. But things are just such as we must meet them and appreciate them in the wide, common corridor of experience. No blind wall separates experience from the world of its interest and love; thoughts and things are part of one divine context. It is through thoughts that we can use things, and things become significant by entering into the context of thought. Thought and things are not two halls, but relationships within one dynamic living world. There is only one window to the significance of the world of things, and that is thought, though things may hang in their own context, without being thought. Whatever varieties of energy science may establish, what- ever identities and equivalences it may trace in the flux of process, one thing is sure, mind which passes in survey the motley array cannot be declared unreal. For mind alone knows itself first hand for what it is, is aware of its own activity and meaning. Whether we find it convenient to make mind thin enough to cover the whole extent of being, or must recognize other types of energy, at any rate mind can never reason it- self out of existence, can never make itself an accident in a world which sets itself the vocation to understand and control. Mind by virtue of its history and claims must be fundamentally at home in the universe. Its purposes alone can make clear the grades and complexities of "being." Mind is not a by- play but, in the words of Plato, "a noble and commanding thing." But " being " is not, as falsely supposed by many an inspired genius, the only door to reality. It has been the habit of man PERSPECTIVE : THE DIVINE FIVE-FOLD TRUTH 5 thus far to emphasize some aspects and read out other aspects of reality, according to his temperamental, intellectual, or prac- tical bias. In this he has usually been right in the importance of the aspects he has read in, and wrong in the aspects he has read out. Thus the Eleatics of all time are quite right, that there must be " being" — stuff, constancies, thickness, grist. But because there must be thickness, must there be absolute thickness, absolute constancy? Could not science and prac- tical life get on with relative constancy? So far as our ex- perience goes, we do so get on ; and in a manner find our way from part to part within the checkered woof of reality. The Divine Truth of Time Instead of writing a poem to the solid, as Parmenides does, why not write a poem, as Heraclitus does, to divine flux, with all its sadness and novelty? Our hopes and aspirations, as well as our doubts and fears, are built upon the consciousness that the universe is not absolutely made, but in the making; that the future may divorce the present, however firmly thought and its object are wedded now — sometimes by altering our attitudes, when the facts we intend seem constant ; sometimes by altering the facts in conformity with our more constant ideals. But our attitudes are facts, too, part of the dance of attention in the ever-shifting focus of object and interest in the drama of experience. Like a magician, time converts the death of winter into the bloom of spring. Like dew upon the flowers, it makes childhood open into youth. Like summer it comes into our veins. Like a lapwing in the night, time steals upon us and we are old. Even while we sleep it trans- forms our values and purposes. Like moth and rust it creeps into our equations and facts. However viewed it is true that reality is vibrant, that it is ever in solution, that it glows. And no static view can ever piece together this motion and life of real process. We can hold only part of reality in the net of our concepts, the rest trickles through. And while the con- stant residue is more important for science, what trickles through may be the more characteristic of life. True, we cannot prove from the fact of change, any particular change or rate of change, nor deny any particular constancy. 6 A REALISTIC UNIVERSE The processes of the universe travel at diverse paces. We must take the substances of the reality which time transforms, each after its kind. But we can prove that if there is change, there must always be change. For, in the infinite aeons, if tune or change were finite, it must have run its course untold ages ago. Change must be taken as real and underived, prior to all our ideal measurements, if it exists at all. This change value, I call time. Let the paean be chanted to eternal time — double- visaged time, with hoar frost on the brow looking backward, and the fire of youth in the face looking forward, fading Autumn and budding Spring in one. If we center our interest on the flowing, the novel and the irreversible, we can easily fall into the mood that only the flow is real ; that the flux is absolute and that there is no such thing as constancy, or truth even in part; that the transforming of the stuff of meanings and of matters is the real and that uni- formities are but illusions. With Omar Khayyam we may come to say : " One thing at least is certain — This life flies : One thing is certain and the rest is Lies ; The flower that once has blown forever dies." Yes, all that is born in the pangs of earthly beauty shall fade and die. This would be infinitely sad, if spring and youth were not reborn with new beauty at the turn of the year. But while "the bird is on the wing," why deny such seeming perch- ings, such constancy as there is, such prediction as experience proves? While the hues of the shadows flit and blend into each other on the face of the mountain in a thunderstorm, still the outlines of the mountain show us the course of the change ; and while the torrent hastens to the sea, the scenery of the banks helps us to gauge its swiftness. So do the more perma- nent fringes of meaning and tendency help us to take stock of the fleeting values of our own life. The Divine Truth of Space And why should not some one write a poem to the void — the glorious expanse of space? For what a congested world this would be if it were condensed into a mathematical point — no looking at each other, no embraces, no starry heavens, PERSPECTIVE : THE DIVINE FIVE-FOLD TRUTH 7 no gravitational equipoises of swinging masses, no differentia- tion of individual centers, no canvas for the cosmic artist to spread his sunsets on, no marshaling of the ranks of tonal har- monies as a result of this absolute condensation — all for want of room. If you have space, you can put as many holes into it as may be necessary, shooting it through with energetic centers, conscious and non-conscious. You can stretch your gravitational threads, you can pour in your luminiferous ether and spread out your electro-magnetic field; you can fill it as full as imagination and convenience may dictate. On its neutral background you can paint as great a variety of star patterns, of cosmic tragedies and comedies, as the necessities of nature and the artistic genius of the universe may prescribe. I would not make space everything, carving a world out of it by means of geometrical figures as some have done. Our imagination at least is too finite to create a universe out of nothing, whatever an infinite mind might do. But, in any case, you must presuppose your space, which you so thanklessly ignore, to have your side-by-sideness of centers, your free mobility, your perfect conductivity. No hindrances there to the wheels of Charles's Wain, no opaqueness to the mercurial messengers of light, — only sublime distances making feeble man's artificial measures, where constellations dart through space to the Pleiades. Viewed from the side of space, your bodies and energies become interferences — departures from the pure limit with which we start. It is true that in the poetry of science, the limitations of space are being annihilated for many practical purposes. The electric network of nerves under human control binds humanity together for social sympathy and cooperation as never before. But it is also true that science has revealed the wonders of space to us in a new light, as its equations of distance, both in the large interstellar world and in the minute interactions of things, bankrupt the resources of our imagination. At any rate, so long as distance thwarts the will's realization in the handclasp of loyal men, the meeting of fond lips, and the em- brace of loving hearts, space must be recognized as real. To divine, neglected space, bespangled with many a star for diadem and begirdled with lightning, let my song go forth. 8 A REALISTIC UNIVERSE The Divine Truth of Consciousness And what shall I say of consciousness, illuminating nature, the manifold world of process and its flow? To be sure, it would not appear except for the complexity of the world of process — its organs and contexts of relations. But they in turn would have no significance or value apart from the divine light of consciousness. It was a noble insight, that of the Sankyah philosophy in far-off days and climes. It is only as nature (Prakriti) develops senses and intellect on the one hand, to match the motley variety of the world on the other, that consciousness can illume the world. It is nature that furnishes the subject and the content too. Consciousness is a neutral light. It adds only the awareness. It cannot be responsible for plurality of egos, .any more than for unity, as the Sankyah supposed. Nor does nature vanish with con- sciousness, but with it becomes significant nature, aware of its pulse beats and its destiny. In itself, consciousness has no variety, no color, no direction. But with it comes to light the color and variety and meaning of this whole checkered, flowing world. No wonder the Sankyah philosophers, with their longing for mystical peace, for the negation of strife and variety, centered their gaze on neutral consciousness and al- lowed nature to vanish with the abstraction of attention. How long before the mysterious awakening ; what vicissitudes of change; what migration of spirit through cosmic spaces; what dizzy ages of evolution of organs and of mind, before my spirit saw the light, who can tell? Who can follow the journey of mind through geologic ages? Who knows whether it is a hardy native plant, grown up hi the cosmic weather of our earth, fraught perhaps with unconscious memory, chastened through suffering, selected by nature's breeding from the simpler stages of life below; or whether it is a divine gift, groping its way in the dark to its father's house? But when consciousness does illumine the patient face of nature, what beauty of significance is there — in part expressed ; in part vaguely felt and only half understood. What opportunity is there for sharing in the directive creation of the divine destiny, which nursed us to this end. Elsewhere, no doubt, the light PERSPECTIVE : THE DIVINE FIVE-FOLD TRUTH 9 has shone before ; soon the light here shall flicker and go out again, as the soul goes forth to its new mysterious birth. All this — the before and after — is hidden in the night of our ignorance, but how glorious to be awake just now, to catch to-night this glimpse of the eternal procession of the ages. Whatever may be the destiny of mind in the cosmic whirl of change, thank God for this. When I take my journey in the sea of energies, midst ethers and star dust, perchance through skies and clouds to stars un- known, perhaps to linger here midst dance of circumstance, who can tell when and how I shall appear ? But I believe that the light of consciousness shall shine for me again ; that I shall see anew the glory of God's world; that I shall feel the sym- pathetic touch in the march of the aeons as I never have be- fore. If so, what does it matter how long I sleep, waiting for the call of God's energies to the beauteous vision? To con- sciousness, lighting the world, in one flash of interest and value bringing groping will and matter face to face, let my hymn be sung. The Divine Truth of Form And, then, what hymn can I sing worthy of the glorious divinity of form? For who would want a chaos of moving pictures like the nightmare of a dream? The consciousness of such a crazy quilt would be even less to be desired than the annihilation of Nirvana. But we have the conviction that some facts are worth more than others. In the shifting and relative shapes of the flux, the soul comes to the insight, now and then, of eternal beauty. Restless sound is woven into harmony, the chaos of color into divine form and expression. The world of things, to some extent, can be recreated into the world of ideals. Who can wonder that Plato found the idea of form, of significant unity, diviner than all the flux in space and would allow to worth alone the prize of being ? Let the materialist claim that beauty is a physiological re- lation; that it depends on a certain structure and its motor reactions. He does not contradict the diviner insight that form — significant relationship — is an original and underived aspect of reality. True, reality must prepare the spirit for 10 A REALISTIC UNIVERSE its realization and appreciation by preparing the organism. Nature must construct an ^Eolian harp to vibrate with the universe of tones. It must invent a photochemic film to give us the many colored rays of cosmic light. In the conflicts of experience it must bring to clearness and distinctness the instinct for fitness and order. Beauty and right come to us first as intuitions, before we can understand or separate the form from the matter. But if we are nurtured in the lap of nature to the end that we may become conscious of form and beauty, then it must be true that beauty suffuses the whole of things; that the flux has worth only as it is sifted through eternal form; that nature's beauty and, still better, our con- scious creation of beauty, is the imitation of a reality of which we have but a vague intimation, an objective world of form, interpenetrating our world of sense, and, in the long series of mutations and survivals of history, constituting our human nature. Looked at from the side of process, nature is a lavish creator, and some of its gifts also have form as read or ap- preciated by human nature. This is not mere chance. It is part of the selective evolution of reality, for human nature is part of nature. Beauty is but nature become conscious of its formal character through its more developed organs of human nature. Thus do nature and human nature conspire to produce the sunset and the symphony. In human nature, nature discovers her own order, recognizes the rhythmic pulse beats of her restless activity. Her immanent tendencies become ideals, her direction organized purpose. And this human nature, while it lightens to an extent the past, is but the prophecy as yet of the larger overarching and over- lapping form toward which the universe in its highest reaches is aiming — that free realization of an ideal where work and play blend in the fluent and joyous activity of spirit. As the music of each passing moment dies into the recessional of the past, one thing remains amidst the changes and chances of clashing masses and souls — the direction of the process. That, at least, is absolute, eternal and divine. What is this direction? Is it more than that the universe in patches ex- presses ideals and so becomes immortalized ? Is there a grand finale? If time is infinite, this should have come to pass in- PERSPECTIVE: THE DIVINE FIVE-FOLD TRUTH 11 finite ages ago. Yet for a superior insight, the patchwork may be a scheme. That it is so remains for us an act of faith — a faith that, in the drift of cosmic weather, " Before me, even as behind, God is, and all is well." This faith like every faith must be justified and transformed in terms of our growing experience. For on the shifting sea of life, the horizon must ever move forward with the progress of the journey, as we steer towards an unknown goal. We can catch the direction in part only by looking backward at the glittering wake of the past. Unseen insights, new adventures, unpredicted accidents confront us in the unknown. But the brave souls who search anxiously for the leading and who follow the light as God gives them to see the light shall arrive. For through it all, we believe, there runs the silver thread of order, the cheering message of the beyond. The conclusion of my poem, which I can but feebly express, shall be that I own the supplementing concreteness, the real thickness of life as all of these, interpenetrating in one common world. Reality reveals itself in five different ways. It has five windows. It reveals itself to our purposive endeavor as a world of restless energies with their relative uniformities. It reveals itself further as time, which in the flux of selves and things gives the lie to the past and creates for the soul new mansions of meaning and value. We must also orient our- selves to space, the playground of energies where the heavens spread out like a curtain and clouds are moved back and forth as draperies. Under certain conditions of complexity and in- tensity, the whole is lighted up by consciousness; and lastly running through it all as the invisible warp of the many-colored woof there must be form — the direction which our finite minds strive to unravel. This is the Divine Fivefold Truth — the five doors which we must enter if we would bask in the divine illuminating wisdom, The night is far spent. The intoxication of soul is wearing off. The cock crows, announcing that matins is at hand. The goddess of drowsy slumber will soon lift her silver veil 12 A REALISTIC UNIVERSE from off the naked earth and depart. The bustling, jostling, wakeful, petty cares will return with the dawn. I thank thee, Spirit, for divine philosophy. May it prove sane when viewed in the glaring light of day. At least the bliss was great, while it lasted. And now into Thy care I commit my mind, while I, too, join the unconscious world in the soft arms of sleep. PAET I ENERGY AND THINGS •c CHAPTER II BEING — MATTER AND THE ABSOLUTE THE story of the concept of being is a long one and consti- tutes pretty much the whole story of philosophy. From Thales down, men have tried to simplify our world by reducing it to some Urstoff, some simple entity or entities in terms of which the motley variety of our world might be expressed and under- stood. It might be water, it might be fire, it might be material atoms, it might be mind, it might be electricity, it might be some combination of elements. In any case 'the human mind has felt more at ease in the world when it has thus simplified it. But whatever may be our opinion of Urstoff, upon one thing we are now agreed, that experience stuff, as revealed in our immediate feelings and sensations, on the one hand, and our purposive construction, on the other, must be the starting point of all our investigations. In terms of this we must differ- entiate and express the problems of the universe in so far as they can be expressed. But is reality through and through experience? 7s Experience Self-sufficient? It has been maintained from time to time, and recently by so brilliant an advocate as William James, that experience is self-sufficient; that our hypotheses "lean on experience but experience leans on nothing but itself" ; and that we have no need, therefore, of any reference outside of experience. While it is true that the process of knowing must thus lean on experi- ence, must take account of the properties and relations, the similarities and differences, the novelties and uniformities as they appear from moment to moment in the stream of con- sciousness, this does not seem a sufficient account of reality as a whole. If we examine the implications of experience 15 16 A REALISTIC UNIVERSE more closel>, we shall find that our experience, at any rate, seems to depend in many ways upon an extra-experiential con- stitution. I shall mention a few cases in which experience, in the sense of conscious experience, implies such a constitution. For one thing, experience does not account for its own con- tinuity, either as involved in intersubjective relations in space or in the bridging over from moment to moment in time. Let us examine the former type of continuity first : in order for two egos to come to an understanding with each other, or to communicate their feelings and ideas by means of "winged words," something more is necessary than their respective fields of consciousness. Certain instrumental processes must be interpolated. There are the physiological movements pro- duced by the speaker, the air waves of the common physical continuum which takes up these movements, and finally the end-organs and nervous system, reacting to these stimuli. Now these intermediate bearers cannot be regarded as experi- ence in their own right. Even the immediatist, unless he is a solipsist, would have to admit that other people's immediacy is not his immediacy, but is communicated by means of inter- mediary processes. This would be true even on a telepathic hypothesis. How it is possible, by means of such non-conscious intermediaries, for conscious egos to meet in a common world, we cannot discuss here.1 In the second place, we cannot account for the continuity of experience in time, any more than in space, as leaning upon nothing but experience. To use James's illustration : Peter and Paul go to sleep in the same bed ; and while not conscious in the meantime, so far as evidence proves, each one, on waking up, is immediately aware of his own past, and one does not get mixed up with the other. Such continuity, bridging over the intervals between our waking moments, must require some- thing besides experience. The reason that experience in wak- ing connects with experience before going to sleep is that both lean for records upon a world of processes which is not experi- ential. The machinery of association, upon which the living- over of experience depends, is not itself experience. The same idea might be illustrated equally well with reference to 1 See Chapter XI. BEING — MATTER AND THE ABSOLUTE 17 social experience or the funded knowledge of the race. Clay tablets, constituting libraries of ancient lore, have been un- earthed in recent years in the Orient. These records of stored- up mind became significant anew as experience, after thou- sands of years, when they were unearthed and deciphered by recent discoverers. Perhaps you retort that they were possible experience in the meantime. But what does possible experi- ence mean in such a case except that they were not experience, until they became continuous, as perception and interpreta- tion, with human beings who stumbled upon the libraries? The phrase "possible experience" only hides the problem; and if it means anything when pressed home, it is that experience sometimes leans upon processes that are not experience. Whether within individual history, therefore, or within the history of the race, it is evident that, when you try to explain its temporal continuity, experience leans upon an extra-experi- ential constitution. What I have shown with reference to continuity might be shown equally well with reference to interest. Take, for ex- ample, a case of primary interest. Why do brilliant things, moving things, loud things, things to suck, etc., fascinate the infant? Not because of experience, surely, because it has no past experience to bank on. If we would find the explanation for such interest, we must go back to biological structure and conative dispositions, not to psychological association. We sum it up by saying that the child and the chicken are so con- stituted as to feel this way in the presence of such stimuli. Evidently experience leans upon what is not experience, as regards primary interest. If you take into account the more general demands or postu- lates that underlie psychological activities, they, too, seem to carry us beyond experience. Why is consistency pleasing and contradiction disagreeable to the cultured man? Why do certain forms and combinations of colors and of sounds stimu- late him to appreciation and excite the feeling for the beautiful ? Why do certain things provoke disgust and other things ap- proval? Partly, no doubt, on account of experience; but if certain instinctive qualifications were lacking, or if the instinc- tive constitution were different, the same situations might 18 A REALISTIC UNIVERSE produce entirely opposite feelings on the part of individual experience. In order to understand the learning process, we must take account, not merely of experience, but of capacity. No facilities for education can overcome the native limitations of the imbecile. And capacity cannot, so far as we can see, be reduced to experience. Imbeciles sometimes come from highly cultured ancestry, and geniuses from a background of ignorant but honest peasants. Not only is the woof of experience-in-the-making thus con- ditioned by an instinctive warp which experience presupposes, but culture and meaning, the net result of experience and tendency, are funded in a way which, to a large extent at least, is unavailable as experience. Physiological and conative tendencies come to do the work of memory. It is precious little that a man out of college twenty years, and engaged in new pursuits, can recall of his college curriculum. And yet he feels differently and acts differently because of his college course. Here, again, in the very definition of culture, we come upon a subtle relation to reality which is not experience. The ego, therefore, whatever else it may be, is not merely a "bundle of perceptions" or of any other conscious states. They are not the whole story, at least. Another road might have been chosen to show the insufficiency of experience as an account of reality. If we take the imme- diatist point of view, what reality can we accord to nature? Is nature merely a " bundle of perceptions ? " We have already found such an account inadequate to the ego ; on closer scru- tiny we shall find it equally inadequate to account for nature. If we insist that the objects of nature are statable merely as our perceptions, we must be prepared to answer several ques- tions. Does reality consist merely in the perceptual differences that things do make, or does it also include the differences which they can or will make under other conditions than the present ? If we admit will and can, have we not implied a larger con- stitution than experience? And, then, what about the con- stancies or uniformities in our perceptions, upon which all our expectancies or scientific laws are based? Is the recurrence of perceptions in different moments of the temporal stream, itself brought about by perception ? Is it part of perception BEING — MATTER AND THE ABSOLUTE 19 that perceptions shall repeat themselves in certain describable and definite ways? But if perceptions do not exist in the meantime, it is hard to see how this repetition can be a char- acter of the perceptions. If esse is perdpi, it is hard to see what reality there can be when there is no perdpi. In the prediction of an eclipse a thousand years from now, or the reading of an eclipse a thousand years ago, there surely is no present perception of the fact ; and absent perception is hardly perception. If there can be such a thing, then, as future perceptions or the reading off of past perceptions, experience must lean upon a non-experiential constitution. This is not the whole difficulty of the phenomenalistic theory of nature. A further problem confronts us. Can an individual, whether conscious or unconscious, be resolved into external relations? Can reality be regarded as having merely an out- side and no inside? By thus regarding it we shall, indeed, avoid the knotty problem of the "thing itself"; but is our account of reality fair and complete? Is reality merely what it does, in the sense of external continuities, waiving for the time being the difficulty of what it may do? In the case of one sort of individual at least, namely the purposive ego, we must admit that he is not merely what he does, not merely the perceptions he produces in us; but he is also something on his own account, a center of at least possible appreciation and willing. This is the real core of the ego for our practical social relations, not the external and adventitious ways of tak- ing him — not his side-by-sideness or likeness to other in- dividuals, not the sensations of the sight-touch-motor complex. The latter for the deeper purposes of our personal relations are merely signs — the clothes, or part of them; and a self consisting merely of clothes would be a funny sort of an in- dividual. The ego, to use a good Hegelian distinction, must be something fur sich and not merely an sich, a meaning and value on its own account as well as something for others. If only purposive beings have an inside, is the baby merely an outside, merely clothes? It seems to have a core of feelings of its own, however crude. It is an object of will and apprecia- tion, of hope and love. And what about animals? Are they merely our perceptual outside with no inside? No, they, too, 20 A REALISTIC UNIVERSE seem to have a core of appetite and feeling which we must acknowledge. And while we know little about the inner life of the simpler forms of nature, at least they are not merely fictions of ours. Our agreements about them are forced agree- ments ; they are not created by convention ; and we must learn to adjust ourselves to these simpler realities in order to control them and to realize our purposes. If we would keep dry in the rain storm we must bring our umbrella and wraps along. While the physical object can to a degree be sensed, while it can even for certain purposes be stated as more or less "per- manent possibilities of sensation," its existence is not constituted by our sensations. Approaching the problem as we must from the point of view of our active purposes, we cannot resolve reality, whether conscious or unconscious, into bundles of per- ception, or into experience of any form, altogether. We must interpolate, somehow, realities which are not immediate ex- perience. Two Hypotheses How shall we conceive this larger constitution? Two im- portant hypotheses have become classical, one that of inde- pendent and immutable substances, and the other that of the absolute. First, a word as regards the hypothesis of sub- stances. The realistic substances may be material or spiritual ; they may be the extended, impenetrable atoms of Democritus or the Leibnizian monads — non-extended, windowless soul- points, representing in an ascending scale of clearness, the entire universe. It is quite wrong, then, to accuse the older realism of being materialistic. On the other hand, the sub- stances which have counted in science have, until recent times, at least, been of the extended or material order. The monads of Leibniz and the qualities of Herbart have not counted in the development of science, interesting though they have been as metaphysical curiosities. The atomic theory of Democritus, adopted by modern chemistry and made exact through Ber- zelius's conception of weight proportions, has, on account of its convenience for scientific description, come to stand as our ideal of atomic realism. In the older conception of atomic realism, the geometric BEING — MATTER AND THE ABSOLUTE 21 properties, depending upon extension, are the important ones ; even after the idea of energy, in the sense of doing work, be- came a permanent concept in physical science, the concept of extension was long allowed to rank with the concept of energy. This gives rise to Herbert Spencer's antinomy as regards extension and force. This antinomy, however, is losing much of its relevancy by the fact that extension is relegated to a secondary place in the scientific conception of physical nature. Some philosophers and psychologists maintained long ago that extension is a "confused idea" and has no reality outside of individual experience. Berkeley pointed out, with his psychological keenness, that the size of a thing varies with the distance and that the form varies with the angle of perspective. He concluded, therefore, that matter, being thus relative, could not be objectively real. Modern psychology, with less of metaphysical interest, but with superior experimental tools, has likewise pointed out the relative character of extension. Thus it is shown that the extension seems longer when the intervening space is filled than when it is empty, whether you take tactual extension or visual extension. Where the area is too small for two points to be discriminated as two, they still furnish the sensation of a bigger point than either of the points separately applied. When a given number of points are made to stimulate the skin cells or the retinal cells successively, the extension seems larger than if the stimulation is simul- taneous. Even as regards sound, we find an interesting rela- tion between the rate of succession of physical stimuli and the sense of volume. Sounds succeeding each other, approximating the rate of 5^5- of a second cannot be discriminated as distinct sounds. We cannot here distinguish even between the dura- tion of the successive and the simultaneous, but the successive feel bigger than the simultaneous.1 Not only the velocity of certain electric currents, therefore, but a certain velocity of nerve currents produces an apparent mass. Modern physical science, however, has been quite untouched by psychological investigation. What physical science has been concerned with has not been perceptual extension with varying conditions, but an artificial unit of extension under i See Chapter XIV, p. 260. 22 A REALISTIC UNIVERSE standard conditions, as, for example, the steel yard kept at a certain temperature, and other uniform conditions, in the British Museum. As long as this conventional unit could be applied under definite conditions, extension still maintained its hold as an ultimate attribute of physical reality. I say physical reality because the field of investigation, where ex- tensive units have been applied, has been narrowed down to this. Philosophy since Descartes has recognized that there is no sense in speaking of an extended will. Even in physical science, however, serious doubts have arisen, though on ex- perimental and not a priori grounds, as regards the absolute character of extension and even of weight. What has given rise to this doubt in recent science is the demonstration that neither extension nor weight can be regarded as an absolute constant, and that, therefore, recourse must be had, for descrip- tive purposes, to a more ultimate concept. It has been shown by Lorentz that even mechanical mass in motion must vary with the electrodynamic field, and so is not constant. Gravi- tational mass, moreover, does not seem to apply with equal force to all energy ; there seems to be little relevancy in speak- ing of electricity as having gravitational mass.1 Recent investigations into the nature of electricity have shown that mass can actually be produced through velocity. Kaufmann, J. J. Thomson, and others have demonstrated "that if the velocity of a charged body is comparable with that of light, the mass of the body will increase with the veloc- ity." 2 And not only that, but the experiments and calcula- tions according to Thomson, "support the view that the whole mass of these electrified particles arises from their charge." 3 1 See "Electricity," by Gisbert Kapp, pp. 10 and 11. 1 J. J. Thomson, "Electricity and Matter," p. 34. 1 It is only fair to say that Thomson in more recent publications has modified his view. As I understand it, he does not now regard it proved that the sum of the apparent masses of the negative charges equals the total mass of the atom. There is a residuum of gravitational mass which must be accounted for in other ways. This is now a matter of controversy. But in any case the Cartesian idea of atoms as rigid, mathematical figures has been exploded. Both the shape and the magnitude of the atom vary with the velocity and the magnetic field. They can be changed by pressure. Energy, not mass, becomes, therefore, the primary physical reality. The atom, Thomson has shown, can be stated as the sum of its internal energy and the energy of translation. BEING — MATTER AND THE ABSOLUTE 23 A number of brilliant physicists, including Rutherford, Strutt, etc., take the view that the atom can be resolved into negative electric charges held together by positive electricity spread over a wider volume. The conclusion of these investigations would seem to be that there is "no mass other than electro- dynamic inertia. But in this case, the mass can no longer be constant ; it augments with the velocity and it depends on the direction, and a body maintained by a notable velocity will not oppose the same inertia to the forces which tend to deflect it from its route as to those which tend to accelerate or to retard its progress." * The new investigations, so far from disproving the descrip- tive significance of the atom as it has figured in physical science, have on the contrary furnished experimental corroboration of its existence and character. Whether the hypothesis of posi- tive electricity proves to be more than speculative, it remains significant that the mass of the atom as now measured coin- cides with the mass of the hydrogen atom, and this would seem to furnish additional evidence for the hydrogen atom as the atomic unit. There is little in common, however, between this present atomism of the electrical school and the old specu- lative atomism. In the new atomism, energy has become the chief interest rather than extension or weight, and it has been confidently asserted that these can be reduced to motion and distance. The atom is no longer regarded as eternal, impene- trable, and indifferent, but as the storehouse of pent-up energy of enormous quantity, though, as in the case of radium, it may be in a very unstable equilibrium. Instead of impene- trable, inert bits, we have now to deal with electrical charges of a positive and negative kind, although it may still be conven- ient to speak in terms of particles or corpuscles as vehicles of charges. Instead of the mythological "bonds" of an older chemistry, we have the relation of positive and negative charges to each other. Atomic relations are explained by the fact that atoms can, under certain conditions, receive or expel 1 H. Poincarg, "The Value of Science," Popular Science Monthly, Vol. LXX, p. 349. For the electrical theory of matter see the lucid exposition by Hon. R. J. Strutt, in his work entitled " The Becquerel Rays and that ^creatiye^ synthesis is of_the very nature of reality We must accept the new qualities and values as gifts, whether it be the compounding of mechanical forces in a new direction, or the properties of chemical com- pounds, or a new life unity, or a new social bond. In each case, we must take account of the properties unique to the specific situation, as well as observe the persisting constants.' In each case, we must follow the lead of experience, and shape our theories accordingly. Each energy system with its prop- erties must be taken as real. It has just such properties and relations as are manifest in the system, whether they be the simpler properties of material systems, or the more complex properties of such systems as life and mind. There is nothing occult about energy, except as our ignorance makes it so. In the second place, systems of. energy, as we find them in There are no closed systems except for our abstract purposes of description. They make definite differences to each other. They interpenetrate and interlock into one energetic world. Energies, throughout the complexi- ties of systems, retain their primal property of doing work. They are ever expended into other energies and reimbursed from them in the great clearing house of nature. The cleavages are of our own making. They are due to our assumptions, not to reality. When, for example, science held to the hypothesis of inert substances, acting on each other by impact — inert, extended, material substances and inert, non-extended, mental substances — as its working model of reality, it was difficult to see how material energy could in any way make a difference to mental. It would be equally difficult to see how it could make any difference to electrical systems, where likewise molecular models do not seem to apply. In either case, we should have to invoke parallelism with its absurd results to bolster up our initial assumptions. But our intellectual models cannot alter the facts. The real units of reality, we have seen, are not PRAGMATIC ENERGISM 53 ijaert entities, but energy systems, in one type of which material properties constitute a differential characterigtic. The ener- getic conception of reality leaves us free to follow the lead of the facts, and to recognize such continuities and discontinuities, such uniqueness and interdependence as we find. Electricity gives rise to mechanical and chemical changes; and they, in turn, serve to liberate electricity ; and while the latter is more subtile and pervasive, it is the material world which canalizes our electrical energies and makes them serviceable. Plant life is dependent upon the material systems for nutriment and framework, and upon light and heat for the processes of assimilation and growth. The mental type of system leans upon the material and organic systems. It requires proper nutriment, proper conditions of temperature and light, proper bodily position, proper rhythms of rest, in order to do its work, not to mention its dependence upon neural structure. It is clear that it is the more complex systems that overlap and are correspondingly dependent upon simpler systems. Heat would seem to be the lowest and most amorphous type of energy from our point of view, as the more complex energies seem to be dissipated as heat, and thus seemingly lost as available energy. But as we have already pointed out, this can hold only for our limited perspective and powers of control. legality reveals_itself in many ^systejns. It is matter, it is light, it is electricity, it is mind, it is truth, right, and beauty. It is all of these and many others. All the varying phases belong to it, and one is no more real than the other. It is " day and night, winter and summer, war and peace, satiety and hunger; but it takes various shapes, just as fire, when it is mingled with different incenses, is named according to the savor of each." l The more complex systems furnish a greater variety of properties, but however imposing they may be, they must trail along and draw their sustenance from the simpler, even as the ivy trails along and draws its sustenance from the soil. While the more complex systems logically overlap the simpler, which they presuppose as conditions and instruments, this does not mean that the simpler have no existence of their own, but are always dissolved or taken up into the more complex. When they 'Adaptation of Heraclitus, fr. 36, Bui-net's translation. 54 A REALISTIC UNIVERSE are so taken up, they cease to exist as simpler. Water, as an individual compound, has definite, characteristic properties; while water, taken up into other compounds, inorganic and organic, is no longer water. It has lost its individuality. But the water that satisfies thirst, with many other unique prop- erties, has claims of its own. We do not want it merely abrogated into more complex systems. We would not want to drink water that has entered as a constituent into blood, or let the children play with water that has been taken up into nitroglycerine.

Here, at any rate, the words of Browning hold : " * * * Nor soul helps flesh More now, than flesh helps soul." Of each, we must say, in characterizing reality: "That art thou." There is no substrate except the interlocking, inter- dependent energies ; no unity, except the form of each, and of the multicolored whole. The passion for simplicity, however, is incurably rooted in the human mind, and there will always be the attempt to reduce the concrete variety of the world into some primordial system, be it matter, electricity, or mind. This seems a mistaken and fruitless quest. We must adhere to the prag- matic postulate without which we could not proceed at all, viz. thatj:ealityjLS_whatj^ contexts. The process is~lundamentally a creative process. It is not a shuffling of neutral entities. The properties are combining properties; they are uniquely determined by the system. We have no right to dogmatize, whether in reading backward from the more complex systems to the simpler ones, or forward from the simpler to the more complex. We must find our way on the basis of experience and take reality as it exists at each stage of complexity. v We can, indeed, classify systems on the basis of common and differential traits; and we find that some can be treated as varieties of one species. Thus it has been found that elec- tricity, light, radiant heat, and magnetism can be successfully dealt with on the basis of a common electronic theory, though PRAGMATIC ENERGISM 55 their differentia are no less significant than before. It has been suggested that nervous energy may be reduced to the electrical type. Says Professor Gotch: "Physiology has defi- nite grounds for believing that, as far as present knowledge goes, both the production and cessation of central nervous dis- charges are the expression of 'propagated changes, and that these changes reveal themselves as physico-chemical changes of an electrolytic character. The nervous process, which rightly seems to us so recondite, does not, in the light of this conception, owe its physiological mystery to a new form of energy, but to a circumstance that a mode of energy displayed in the non-living world occurs in colloidal electrolytic structures of great chemical complexity." While science thus seems to have succeeded in simplifying large domains of facts, so long seemingly heterogeneous, it has also discovered new varieties and complexities which challenge further reduction and corre- sponding overhauling of old categories, as in the case of radio- active energies. $
